IMPROVEMENT IN TOILET-BRUSHES.

Specification forming part of Letters Patent No. 124,409, dated March 5,1872.

e Know all men by these presents:

That I, ALDEN WILDER, of Hingham, in the State of Massachusetts, have invented a new and useful Improvement in Brushes, of which the following is a specification:

In the accompanying drawing, Figure 1 shows the recessed backing; Fig. 2, the block with bristles wired in; and Fig. 3 is a section of the two put together.

This invention consists in the adaptation and arrangement of parts of a toilet-brush to be made of cements, based on pitch, resins, or gums, becoming easily plastic under thermal influences, and forming, with coal, stony matter, sawdust, and vegetable material in powder or fiber, and with coloring matter, a cement hard and inflexible at ordinary temperature, but readily plastic at temperatures considerably above the ordinary temperature of air or of the human body. These cements are all soluble in one or other of the common solvents, alcohol, ether, essences of various kinds, but not in water, and are all of them, or nearly all, capable of being drilled.

These properties are what it is proposed to 'use in this invention, and the invention is carried into operation as follows: The backing of the brush is first molded into shape, having a recess formed to receive the bristle-block, as shown at a. Abrush-block or bristle-block, b, is then formed by molding or turnin g, or shaping of the exact size and depth of the recess, or it may be alittle deeper or shallower, as the fancy may determine; the same depth is probably the best. This block is then drilled as brushblocks are ordinarily drilled, and the bristles set and wired in, as they are set and wired in wooden blocks. The recess of the backing is then either coated on its inside with a solvent for the cement, or, what is better a liquid cement is made based upon the principal agglutina-ting material of the cement, dissolved in a suitable solvent, such as alcohol, ether, or essence. In case of mostof the compounds used for these purposes, a solution of shellac in alcohol is as good as any thing-perhaps the best of any. The backing-recess, or the lock, or both, are coated with this liquid cement, and fitted and pressed together and the brush is complete.

Brushes made with the bristles merely inserted in the cement, and the cement, while hot, pressed round them, are very subject to lose their bristles; and if the bristles are inserted through a metallic plate or wooden block, the unequal expansion and contraction of the block or plate under thermal or hygroscopic influences causes a speedy destruction of the brush. But, by the use of the same material for block and backing, and wiring in the bristles, the desin ble result is reached.

I, therefore, claim- As a new article of manufacture, a brush composed of a recessed backing and bristlebloek accurately fitted-therein, both made of cement plastic under thermal influences, and having the bristles wired into the bristleblock, when united by liquid cement or solvent, substantially as described.
